Installation, operating and maintenance instructions
• Electricity warning (hazardous voltage)!
»
Failure to observe the hazard may result in death, injury or damage to property.
→ Before performing any work on conductive parts, always disconnect the unit completely from the elec-
tricity supply and make sure that it cannot be switched back on again.
The electrical installation may only be carried out by qualified electricians in compliance with the installation, operating and mainte-
nance instructions and the applicable national regulations, standards and guidelines:
■
ISO, DIN, EN and VDE specifications, including all safety requirements.
■
Technical connection conditions.
■
Safety at work and accident prevention requirements.
This list does not claim to be complete.
Requirements should be applied under one‘s own personal responsibility.
■
The electrical connections must be made as shown in the corresponding wiring diagrams and terminal diagrams.
■
The type of cable, size of cable and method of laying should be determined by an authorized electrician.
■
Low and extra-low voltage cables should be laid separately.
■
An all-pole mains disconnection device with at least 3 mm contact gap must be provided in the supply line.
■
Use a separate cable inlet for each cable.
■
Any cable inlets that are not used must be sealed so that it is airtight.
■
All cable inlets must have strain relief.
■
Create equipotential bonding between the unit and the duct system.
■
Check all protective measures after the electrical connection work (earthing resistance, etc.)
■
Motor current and motor power must not exceed the values stated on the motor nameplate. The specified max. fan speed must
never be exceeded, otherwise the motor and fan will be destroyed by this overload and dissolved or flying parts can destroy
other components.
12.1. Unit supply cable
12. ELECTRICAL CONNECTION
Connect the mains supply cable as shown in the wiring diagram. For the dimensioning of the line, observe the unit‘s rating plate and
the relevant guidelines. Appropriate protection with correctly dimensioned automatic safety breakers (circuit protection breaker)
must be provided.
The device must be connected according to the wiring diagram. For fans which are controlled by external control devices, the corre-
sponding operating instructions of the manufacturer must be observed.
12.2. Thermal motor protection
During operation, electric motors heat up. Under certain circumstances (excessively high ambient or fluid temperatures, heavy con-
tamination, etc.), the motor temperature may exceed the safety limit of the electrically isolated parts.
Applies for versions with led out thermal contact: No warranty in case of a not connected Thermal Contact. Damages caused by
overheating will not be considered.
